Being a full stocked PA long rifle, that pretty much created a
38 inch rain gutter back the stock, under the water proof baggy, and right into the lock! <img src="/ubbthreads/images/graemlins/crazy.gif" alt="" /> Even after removing the touch-hole and manualy priming the barrel, she still did a pretty bad hang-fire when I popped her off for cleaning!
Is your stock sealed under the barrel? An oft-recommended procedure is to seal between the barrel and stock with furniture paste wax when you're putting the barrel back in. Did you use a bit of beeswax to form a dam in the angle between the barrel and forend just ahead of the lock? Those two things help a good bit in keeping water from running/seeping into the priming when one forgets to keep her muzzle down. I also put a bit of grease, paste wax, or beeswax in between the lock and the barrel to seal that potential wick. The excess squeezes out when I tighten the bolts up and is scraped off.
Then, as mentioned, there's the use by some of vaseline or grease to seal around the pan and/or between the pan cover and barrel, that some swear by. I haven't hunted in the rain enough to have a strong opinon on these, but they don't help much if water can get in from beside or under the barrel.
